I thought they'd proved now that Man-Flu is a genuine ailment:

Different viruses, different effects vary from punter to punter.
Health seems to have a bearing on it. Can see off old punters.

I had an odd one recently.
Didn't suffer that much but was knackered most of the time for 3-4 weeks. Often the brain would not work right - yes even worse than normal
Hardly slept for about 4 nights near the beginning. All sorts of gunk coming out of my nose and lungs, tiny improvements every day.

Usually colds bounce off me. Rarely have them and usually 90% gone in 3 days

It seems like we should be watching out for signs of "Aussie flu" which is not a joke.

The H3N2 strain, known as "Australian flu" or "Aussie flu," has been linked to a number of deaths in Ireland.
It has the same symptoms as common flu - including a high fever, exhaustion, a chesty cough and a sore throat.
A flu epidemic has also hit France, claiming at least 30 lives.
Eight of the 53 people treated in intensive care units in Scotland in the past fortnight have died, including an 18-year-old girl.

Hospitals in England have also been seeing very high rates of patients with flu, with a sharp rise in cases seen by GPs in the past week - up 78% on the week before.

I might confirm with my Doc that Aussie Flu was part of the jab I had.

My wife's flying back to Britain for a few days. I hope she doesn't bring me back any "presents". Colds and Flu are bloody awful. People being made to turn into work ridden with disease is a big part of it spreading IMHO. Employers only lose more sick days and/or productivity as a result.

Aircraft and airports are a great place to pick up diseases

I used to have Flu Jabs & was always really ill afterwards. Since i stopped having it over two years ago ive not had a single cold..

I think i read a while back that there is a cure but under trials for years yet. 

Still in Cyprus, Andrew?
